As eeek2121 says: entirely possible.
I get a 5-figure payment monthly (thank Adsense - love ya!) and work with other publishers with 4-5 figure monthly incomes .
You definitely need to work smarter/harder now than you used to. With Google coming down heavily on sites using any promotional methods they don't agree with it is smart to diversify traffic sources, build loyalty etc rather than some of the more 'traditional' ways of tackling niche sites.
Same goes on the AdSense front: You used to be able to keep turning to screw to increase CTR without any downside. Now you need to much more mindful of customer experience if you don't want to see either traffic of CPC dropping off a cliff.
